I just completed a weekend duffle bag in a Craftsy Project Class. I used PE to draw the bag pattern pieces, and there were a lot of them. The instructions gave the dimensions and number of pieces to cut.

Very nice indeed! I have made a duffle and a purse. I was happy with them when I was done but I felt like they were too "putsy" and too much time for what I got out of them. I guess I just get more satisfaction out of making garments. I will probably forget the pain and make another bag some time, since I have the materials. LOL.
